The UFC invades Atlantic City tonight for the first time in seven years.

The show, featuring a main event between lightweight contenders Gray Maynard and Clay Guida, airs from the brand new Revel Resort and Casino on FX beginning at 9 p.m. With a win, Maynard or Guida would put themselves in the mix for a lightweight title shot.

Maynard is coming off two straight title fights against Toms River, N.J., native Frankie Edgar. The first was a draw and the rematch was an Edgar knockout victory. Edgar has since dropped the title to Benson Henderson and those two will meet at UFC 150 in Denver on Aug. 11. Guida, a fan favorite, is coming off a decision loss to Henderson in November.

UFC on FX 4 will be the first athletic event to be held at the new Revel Resort and Casino’s amphitheater. The venue seats 5,500. The organization held six shows in Atlantic City between 2000 and 2005, establishing its new identity under the unified rules of mixed martial arts, but hasn’t been back since.

In the co-main event, Sam Stout will meet Spencer Fisher in a battle of hard-hitting lightweight journeymen. Brian Ebersole takes on T.J. Waldburger in a welterweight matchup and featherweights Ross Pearson and Cub Swanson square off.

UFC is back in action tomorrow night from Belo Horizonte Brazil. Legendary fighters Wanderlei Silva and Rich Franklin meet for a second time in the middleweight main event.
